Dependence of coincidence frequency in double-glazed window on glass thickness and interpane cavity

The dependency of transmission loss (TL) and coincidence frequency on front pane thickness, interpane distance, and back pane thickness of double grazing window were investigated, and the results were compared to previously published ones to test the consistency of our finding. The coincidence frequency shifted toward low frequency as back pane thickness increases. This tendency was independent of interpane distance and measurement conditions.
